Phone and social media

Screens are not as harmful as headlines say, but using less social media gave small mood gains in trials. Fewer notifications and a phone out of reach at meals are easy places to start.

Why it matters

The overall link is small. Across three large surveys of over 355,000 teenagers, technology use explained at most 0.4% of the differences in wellbeing [1]. That’s a small negative link, and it’s about teenagers, not adults. Screen time is not the main thing that decides how you feel.

Using less social media helped a little in trials. In one trial, 143 university students limited Facebook, Instagram and Snapchat to 10 minutes each per day for three weeks. They felt less lonely and less low than students who used them as usual [2]. In a much larger US trial, people paid to deactivate Facebook for four weeks reported slightly better wellbeing, about 0.09 standard deviations. They gained about an hour a day, spent more time with friends and family, and used Facebook less afterwards [3]. Small effects, but real ones, from randomized studies.

Phones at the table. In a restaurant experiment with over 300 people, those told to keep phones on the table felt more distracted and enjoyed the meal with friends or family less than those told to put them away [6]. An older study found that just having a phone in view made strangers’ conversations feel less close [4]. A close replication with 356 people did not find that effect [5]. So using the phone during time together seems to matter more than it simply being there.

How to do it

• Turn off most notifications. Keep calls and messages from real people. Switch off news, shopping, games and social apps. In a trial of 237 people, getting notifications in three batches a day improved mood, attention and sense of control. Getting none at all made people more anxious about missing out [7]. So batch, don’t cut off completely.
• Put the phone away when you’re with people. In a bag or another room, not face down on the table.
• Move social apps off your home screen, or log out after each use. A small step before opening an app is often enough to skip it.
• Set a daily limit for social apps using your phone’s built-in screen-time settings. Thirty minutes total is a reasonable target based on the student trial [2].
• Charge it outside the bedroom. That keeps it out of your last and first minutes of the day. sleepgood.now has more on screens and sleep.
• Grayscale mode made people use their phones less in a trial of 112 people, but it didn’t change wellbeing [8]. Try it if you want less screen time, but don’t expect it to lift your mood.

Common mistakes

• Going cold turkey, then bouncing back within a week. Limits and fewer notifications last longer.
• Replacing one app with another. If you cut Instagram and spend the same time on news, little changes.
• Assuming screen time is the cause of every bad mood. The effects are small. Sleep, movement and time with people usually matter more.
• Ignoring what you lose. Group chats and video calls can be how you stay close to people. Keep those.

Evidence

Rated Some. Several randomized trials found small benefits from using social media less [2][3], and one from batching notifications [7]. But the student trial was small and short, the effects are modest, and the large survey studies show only a weak link [1]. The “phone in sight” effect did not replicate [5], while actively using it during a meal did reduce enjoyment [6].
